concern: I, Leon Saw'rnnuz Hows, a citizen of the United States, residin in the city, county, and State of New have -invented certain new and useful Improvements in Box-Strapping, of which the ollowing is a full, clear, and exact description. My invention relates to metallic box strapping, the main object being to provide an improved construction whereby such strapping may be easily nailed in place on a box, and whereby when in place it will guard the from contact with the nail head or heads floor, so that the box to which the strap is applied may be easily pushed over the floor without'scratching or tearing the same.

ox strapping, as ordinarily employed, is

To all whom it may 1 represents the Be it known that main body of the strap. The outer side of the strap along a central ling is knurled or corrugated transverselyas at 3-3 are raised bosses on the outer surface of the strap and on opposite sides of the urled portion 2. n Fig. 1, the strap is knurled throughout its length. In Fig. 2, I have shown a nail 4 standing obliquely, with its sharp end resting in one of the knurls to fromsslipping when a blow is given iiicientto penetrate or to punc- Continued driving of the en the head e tops of the box is placed upon the floor, said bosses will support the box and enable it to be moved around on the floor without tearing the latter. The bosses may e provided ment, the able, they b intervals to guarantee a ful the nail heads used in securing the strap in ace. p The knurled portion 2 may extend throughout the length of the stri as shown in Fig. 1, but, if desired, may only occur at intervals, as shown at 2-2, Fig. 4. It is preferable to strap to hug tightly to the box;

nail is fully driven into place, the nailed at intervals to the box. In applying thereof will stand below th such straps, it is more desirableto drive the nail obliquely, so that as the nail is driven in. the draft of-each'nail will be in a direction to tighten the strap. In view of the smooth surface of strap, practically impossible to puncture the metal, with a nail which stands obliquely when it is being driven. is common practice to the metal by f v k the strap with the nail placed vertically. Vhen the puncture is turned obliquely, as driving is continued. he swinging "of the nail from the vertical to the ob ique position provide the knurled portions tends to prod in all instances between adjacent sets of t e strap, so that bosses, so that te nail heads Will be pro receiving the last few blows, is insuflicient to tecte by more than one or two bosses properly tighten the strap. By my improve- Again, by so locating-the knurled portions ment the nail may be placed at an angle to between the bosses. the nails Wlll be en ered the strap preparatory to puncturing the latter. and may be driven without danger of slippage, every blow on the nail being to produce a drag on the strap e osses so that the not likely to encounter the bosses and flatten them down. By having the bosses occur at intervals, as shown, the space between successive bosses on one side furnishes a space edge of the nail head on a strictly irection which will take up the slack and cause said strap to hug tightly to the box. hese and other advantages will be apparent to the mechanic skilled in thisart, 0m a reading of t e f0 owing specification.
